Keeping a pool clean and clear is a delicate balance of filtration, chlorination, alkalinity, calcium hardness and pH levels. Bather load and organic matter (including body fats, fluids and sweat) can quickly throw a well-balanced system out of sync.
In commercial and community pools the most important consideration has to be the cleanliness and safety of the pool water for bathers. The water treatment systems we construct are often large and complex. Pool owners and operators have choice when it comes to sanitation and disinfection of the water in their facility, and no two systems are ever the same. Ultraviolet Sanitation in commercial applications has long been used to support the removal of pathogens and bacteria, but the role it plays in making the pool more comfortable and the water less irritating on skin and eyes is an added benefit in some cases.
Our team have always been particularly interested in the effects UV systems have on Combined Chlorine levels in our clients pools. Especially those indoor pools, where no natural UV exposure occurs. When we were recently asked to install a UV system for a long term clients, we knew this was a perfect opportunity to see the difference the system could make to the water quality, but in particular the levels of combined chlorine in the pool.
Thankfully our client was as interested in the results the new equipment would make to their water quality and agreed to let us use this upgrade for our own research. We started by taking a variety of different readings from the Learn to swim pool where the system would be installed, and monitoring those levels immediately after the system was turned on and for a number of days afterwards.
For full details and information about Combined Chlorine and UV Sanitation we have developed a fact sheet on the upgrade that features a ProMinent UV system which can be downloaded below.
